Replace direction definition PCI_DMA_BIDIRECTIONAL with DMA_BIDIRECTIONAL, because it helps to enhance readability and avoid possible inconsistency.

Applied to drm-intel-gt-next, thanks for the patch. -Daniel
Hi, just in case, a similar patch received some (unrelated) comments a few weeks ago. See [1].
Should it rings some bells to someone who know who knows what should be done.
Just my 2c.
Hm yeah there's some fishy stuff in here, but it's cc'ed to intel-gfx so should get picked up there. -Daniel
